Abstract (en)
[origin: WO8910473A1] A brake light switch circuitry has an additional switch (S2) which opens upon actuation of the brake pedal (13) but only after the first switch (S1) closes. The signals from the two switches are processed by gating circuitry (16, 17, 18) to produce brake signals (BS1 and BS2) which are used respectively to provide a stand-by idle-running or idle-setting signal (LL<*>) and to switch off constant vehicle velocity control (FGR) by the main computer (30) of the EDC. It is thereby prevented that, in the event of the brake switch (S1) becoming faulty and remaining closed during an overtaking maneuvre, the EDC does not reduce the injected fuel quantity to the idling quantity, even though the accelerator pedal is depressed. It is also prevented that, in the event of a fault in the brake switch (S1), while the accelerator pedal is released, constant vehicle velocity control by the EDC is not switched off.
